The verb "study" and its third person singular form "studies" are both transitive; some object of the verb specifying what is to be studied is required for a complete clause containing this verb.

Helping verbs are typically intransitive because they do not require a direct object to make sense in a sentence. They function to help the main verb in expressing tense, mood, or aspect.
Transitive nouns don't exist. There are, however, transitive verbs. Transitive verbs must have a direct object. For example, "holds" is a transitive verb because it requires a direct object. "She holds" is not a complete thought, but "she holds flowers" is.

"Chirped" can be both a transitive and intransitive verb. As an intransitive verb, it stands alone without requiring an object (e.g., "The birds chirped"). As a transitive verb, it requires an object to complete its meaning (e.g., "The birds chirped a lovely tune").
checkers is the direct object so play is transitive
